介绍了EAST离子回旋射频（ICRF）天线真空馈通的详细设计，并进行了沿着电分析和热结构分析。研究了真空馈通中的电场、电压驻波比和应力。采用无氧铜环作为缓冲垫，宏束等离子弧焊接的方法，保护陶瓷在焊接过程中不受损伤。介绍了真空馈通装置样机的真空泄漏试验。
Detailed design of the vacuum feedthrough for the ion cyclotron radio frequency (ICRF) antenna in EAST, along with an electro-analysis and thermal structural analysis, is presented. The electric field, the voltage standing wave ratio (VSWR) and the stresses in the vacuum feedthrough are studied. A method using the rings of oxygen-free copper as the cushion and macro-beam plasma arc welding is applied in the assembly to protect the ceramic from being damaged during welding. The vacuum leak test on the prototype of vacuum feedthrough is introduced.
